Profile of Anti-Tp47 antibodies in patients with positive serology for syphilis analized by western blot BJID
Miranda,Ana Paula Félix de; Sato,Neuza Satomi.
In Brazil, syphilis is still a great problem of public health. Serological test is essential for syphilis diagnosis and the current trend is the use of recombinant antigen in the treponemal tests, due to its confirmed higher sensibility and specificity. The purpose of the present study was to analyze the profile of anti-Tp47 antibodies in patients with positive serology for syphilis. One hundred positive sera samples were analyzed by Western Blot (WB) technique, using the recombinant antigen (rTp47). Ten of them did not present antibodies against the fraction rTp47, the results were confirmed by WB using native T. pallidum antigen. All ten samples had antibodies against the fractions Tp17 and Tp15 and presented low reactivity in VDRL, negative results or...

Sensitization study of dogs with atopic dermatitis in the central region of Rio Grande do Sul Arq. Bras. Med. Vet. Zootec.
Pereira,D.T.; Cunha,V.E.S.; Schmidt,C.; Magnus,T.; Krause,A..
Canine atopic dermatitis (CAD) is a common dermatosis, defined as a genetic-related disease which predisposes to skin inflammation and pruritus, associated to a IgE-specific response in most of cases. Clinical diagnosis may be later complemented by skin allergy and/or serological tests. The aim of these tests is to identify possible allergens in order to enable the clinicians to select candidate antigens for allergen specific immunotherapy. In the present study 58 CAD positive animals were tested. All were submitted to the intradermal test (IDT) and screened for the presence of antibodies against different antigens using ELISA. The obtained results show a high prevalence of sensitization among the tested dogs to house dust mites and to pollen ofC....
